Abstract:

 


In this
study, Diquat 200 g/l herbicide was tested against to weeds causing damages in
peach orchards of Samsun province in the Black Sea Region in 2017. The
experiment was carried out in 9 blocks (6 doses of target herbicide+2 doses of
reference herbicide+control) with 4 replicates in 2mx25m=50 m2 parcels
according to randomized blocks trial design. Herbicide effects in formed groups
according to variance analysis with Tukey test (5%) in the JMP program were
found to be different and significant, statistically.Weed density in peach
gardens in Samsun region; shepard's purse(Capsella bursa-pastoris), bluegrass
(Poa annua), sow thistle (Sonchus oleraceus), hooked bristlegrass (Stellaria
media), brome grasses (Bromus spp.), Henbitdeadnettle (Lamium amplexicaule),
field marigold(Calendula arvensis) and pimpernel (Anagallis arvensis) was
evaluated as being very intensive because it is more than 10 in m2. In
Post-emergence in peach gardens, Diquat dipromide (200 g/l)active
ingredientherbicide was applied at the doses of 300, 400, 500, 600 and 1200
ml/da while Roundup Star Glyphosate Potassium Salt was applied at the doses of
300ml/da, respectively against to post-emergence weeds in peach orchards.
Diquat dipromide (200 g/l)application at the dose of 300, 400, 500 ml/da was
found ineffective against to both broad and narrow leaf weeds. At doses of only
600 and 1200 ml/da, the killing efficacy of herbicide was found at 90-100% both
narrow and broad leaf weeds . For this reason, Diquat dipromide (200 g/l) was recommended
as herbicide after discharge at a dose of 600 ml/da, which was found to be
effective at 91.71% for eight weeds in the garden. Phytotoxic effect on peach
trees was not observed at the dose of diquat dipromide 1200 ml/da.
